Research direction

Start by reproducing on Vintage Story 1.22.7 with Optimum and Doden’s Landscapes, then compare against Optimum alone and vanilla. Record the render distance, mod versions, and client log, and trace whether LOD, chunk culling, or a mod interaction shortens terrain visibility. Done means preserving the configured vanilla distance or documenting a limitation and preventing the rendering issue from disconnecting the client.

Description

bug compatibility complexity: hard rendering

Report

A Vintage Story player reported multiplayer disconnects while using Optimum with Doden's Landscapes, an LOD terrain mod. The report says vanilla terrain does not render to the selected view distance when Optimum is active. The user disabled Doden's Landscapes to check whether that mod alone caused the behavior and still observed the problem. They tested with Vintage Story 1.22.7 and few other mods.

Source: Optimum ModDB comment.

Expected behavior

Optimum should preserve the configured vanilla terrain render distance. If its LOD or chunk visibility logic intentionally changes that distance, it should not cause a client to disconnect from a world.

Actual behavior

The reported visible terrain range is shorter than the configured vanilla distance, and the player's world connection is reportedly lost during the same setup.

Investigation and acceptance criteria

  • Reproduce on Vintage Story 1.22.7 with Optimum and Doden's Landscapes, then compare with Optimum alone and vanilla.
  • Record the render-distance setting, Optimum release, Doden's Landscapes version, client log, and whether disconnects recur when terrain visibility is corrected.
  • Identify whether the difference comes from Optimum's LOD, chunk culling, or a mod interaction.
  • Preserve the configured vanilla view distance, or document a deliberate limitation and prevent the rendering issue from disconnecting the client.
